In the present embodiment, the connection mechanism 22 may be provided on the same side of the lifting mechanism 21 and the extension table 23. For example, the lifting mechanism 21 and the extension type workbench 23 are arranged on one of the front side, the rear side, the left side and the right side of the lifting mechanism 21, the lower end of the lifting mechanism 21 is fixedly connected or detachably connected with the lower end of the connecting mechanism 22, the upper end of the lifting mechanism 21 and the extension type workbench 23 are optionally in contact with the middle part of the connecting mechanism 22 and form a sliding connection at the contact part, and the extension type workbench 23 is driven to slide up and down on the connecting mechanism 22 when the lifting mechanism 21 performs lifting motion. In actual production, the mode of arrangement may be selected according to needs, and is not particularly limited herein. The lifting mechanism 21 may be provided above the extension table 23, or may be provided below the extension table 23. When the lifting mechanism 21 is disposed above the extension type workbench 23, the upper end of the lifting mechanism 21 is connected to the lower end of the traction device 1, and the lower end of the lifting mechanism 21 is connected to the extension type workbench 23, so that the connection mechanism 22 may not be required, but this way easily causes the extension type workbench 23 to be separated from the connection protection of the lifting mechanism 21 when a failure such as a breakage occurs in the lifting mechanism 21, and the extension type workbench 23 falls from the high altitude. In view of this, in the present embodiment, it is preferable that the lifting mechanism 21 is provided below the extension table 23, and the connecting mechanism 22 is provided to connect the extension table 23, the lifting mechanism 21, and the traction device 1, so that even if the lifting mechanism 21 breaks down, the extension table 23 can be hung on the connecting mechanism 22 without directly falling off, thereby further ensuring the safety of the worker 200 during the inspection work and improving the safety of the inspection vehicle during use.

When the extension type work table 23 is extended and opened along the width direction of the track beam 100, the length of the extension type work table 23 is increased, and when the lifting mechanism 21 is extended to drive the extension type work table 23 to ascend, the height of the lifting mechanism 21 is increased.

Furthermore, the telescopic assembly 213 is a telescopic hydraulic cylinder, so that the control is stable and the bearing capacity is high.
Alternatively, as shown in fig. 5, the connection mechanism 22 is a column structure, and the groove structure 221 is disposed on the column structure, and the groove structure 221 penetrates through the column structure along the width direction of the track beam 100.

In this way, when the extension work platform 23 goes up and down, the connecting beam 2312 can go up and down in the groove structure 221, and not only can the two groove walls of the groove structure 221 located in the up-down direction be used for limiting the lifting displacement of the connecting beam 2312 and further limiting the lifting displacement of the lifting mechanism 21, but also when the lifting mechanism 21 goes wrong, the lifting mechanism 21 can be ensured to be hung at the groove structure 221 of the connecting mechanism 22 and not to directly fall off, so that the further protection effect is provided for the worker 200 standing on the extension work platform 23.
Optionally, the size of the groove structure 221 in the vertical direction is greater than or equal to the lifting stroke of the lifting mechanism 21. The lift stroke of the lift mechanism 21 is a height at which the extension table 23 is raised when the lift mechanism 21 is raised from an initial contracted state to a predetermined position.
